INFLATABLE TIRE.

Application filed July 25, 1923, Serial No. 653,815, and in Spain February 2, 1923.

The invention relates to inflatable tires, and more particularly to that class of tires which are equipped with a supplemental air chamber.

it It is an object of the invention to provide a tire in which a protective casing surrounds the supplementary 'air chamber and is secured to the telly of the wheel.

A further object consists therein that the w protective casing for the supplen'ientary air chamber is secured to the folly and to an intermediate portion of the wheel disk, the latter forming with a portion the comple ment of said casing.

With these and other objects in View, the invention comprises the means described in the following specification, particularly pointed out in the claim forming a part thereof, and illustrated in the accompanying so drawing, in which,

Figure l is a fragmentary section through a disk wheel to which my invention has been applied ,7 and,

Figure 2 is a similar section of a. modili- 155 cation.

Referring to Figure 1 of the drawing, the Wheel includes a disk d which at the circumference is bent to provide a horizontal flange constituting the telly. On the latter is 39 mounted a rim 0 to which is secured a tire casing 0;, which is hollow to provide a main air chamber 6. To the inner side of the telly secured an interior telly band 7 which carries an annular protective casing e. The

latter houses a rubber hose 3),, constituting a supplementary air chamber which is placed in communication with the air chamber 5 through a tube 72,. A valve 4) afi'ords means for admitting air to the chamber 5 .end is secured to an intermediate portion of In the modification shown in Figure 2, 40 the interior telly band is dispensed with. The protective casing for the supplemental air chamber is afiorded by the disk d of the wheel and by a curved plate 6 which at one the disk CZ, and at the other end is secured to the telly is which is formed integral with the disk. lhus, the plate 6 complements a portion of the disk and the telly to provide a casing for the supplemental air. chamber. The construction and operation of this modification is in all other respects the same as in the first described embodiment.

While the drawing shows the preferred embodiment of the invention, numerous as changes and alterations may be made without departing from the spirit of the invention. I, therefore, do not wish to limit myself to the particular details as shown, but wish to include all changes, alterations, modifications, revisions and re-arrangements constituting departures within the scope of the invention, as defined in the appended claim.

I claim:

In a vehicle disk wheel, the combination with a telly formed integral with the wheel disk, of a tire having an air chamber and mounted on said telly, a supplementary air chamber mounted interiorly of said telly, means for placing the air chambers in conimunication and aprotective casing surrounding said supplementary chamber, and secured to said telly and to an intermediate portion of the said wheel disk, the latter forming with a portion the complement of said casing.
